Oculus Integration Unity Asset - Haptics not working on Rift S
I'm trying to use the Oculus Integration Unity Asset (version 1.42) to get haptic feedback on the Rift S controllers. In the past I've used OVRHaptics to do this but I see this has been deprecated now (even though I've tried OVRHaptics and that doesn't work on Rift S either) So I'm trying to use OVRInput.SetControllerVibration and I'm just getting no haptic feedback at all on either controller. If I use the built in UnityEngine.XR InputDevice.SendHapticImpulse, then I get haptic feedback on the Rift S just fine so the haptics are working fine on the controllers and are working fine within Unity. But no matter what I try, I cannot get the OVRInput.SetControllerVibration or the OVRHaptics stuff working at all on the Rift S Am I missing something or is this just broken somehow in the SDK?
Unreal 5.3.2 OculusXRInput crash caused by haptics
Hey, I've been having an issue with using haptics. I upgraded from unreal 5.1 to 5.3.2 and updated the MetaXR integration package to V60.0. After the upgrade, using "Set Haptics By Value" or "Play Curve Haptic Effect" both cause a crash in Editor and in the Meta Quest 2&3. When removing these from my BP, the crash does not occur. Did something change to the haptic functionality? Am i missing something? Sincerely, RaymondNative Quest haptics / vrapi_SetHapticVibrationBuffer
I am adding haptics to my Native SDK project for Go/Quest. I find in the headers a vrapi_SetHapticVibrationSimple where you pass in 0-1. So that's straightforward. However I also find a vrapi_SetHapticVibrationBuffer that takes a start time, a number of samples, "true if this is the end of the buffers being sent", and a series of unsigned char samples. How do I use this? This looks very useful but I am looking hard through the Native Quest documentation and there is no documentation for haptics for the Native API. Things I would like to know: * Can I use this feature? The only reference I find to haptics buffers on the website is this older documentation for Oculus Touch on desktop, which says the feature is deprecated. But it is used in the VrController sample in the native SDK so I assume it is deprecated on Desktop only and not Mobile. * Is there an upper bound on the allowed duration/length of a ovrHapticBuffer? * What is the exact interpretation of the sample values? 0 is no intensity, 255 is max intensity, I assume? * What is the memory ownership of the HapticBuffer member of ovrHapticBuffer? Will vrapi retain a pointer to this buffer? May I safely free/alter the buffer immediately after calling vrapi_SetHapticVibrationBuffer? * Is there a value (such as 0) for BufferTime which will be interpreted as "begin playing immediately"? * Can I use this feature to set a vibration frequency? If so, how? The Unity and Unreal Quest documentation have "frequency" parameters on the haptics methods for those APIs but vrapi_SetHapticVibrationSimple does not. * Should I expect the feature to work on Go? Are there differences in the haptic behavior between Go and Quest?
Meta Haptics Studio Feedback and Question
We have been using Meta Haptics Studio with success, however, when manually editing the .haptic files there seems no way to shorten or lengthen the total haptic sound, I can see in the SDK that the length used is the total length (not selected length), is there a hidden feature, or is this not possible? As this is a tool feedback forum, these are the feature requests we would love in Meta Haptic Studio: Trim the length of the haptic Add length to the haptic (even just a length thing) Assign relative paths from a project source to each folder to export (we use folders that contain feature sets, not lots of function based folders, so a footstep haptic would be in the character/haptics folder not all under 1 haptics folder) Removal of source files (no need for them once design is good) Sub Groups of Haptics (We have a-lot) Export as Wav (for other systems, but allows us to focus on Quest first)Touch haptics amplitude/intensity - what is the range, and in what units?
Hi - I'm developing an experiment with Quest 2 in Unity that uses haptics with variable intensity. In Unity, we're given a range of 0 to 1, where 1 is the maximum intensity the Touch controller can deliver. I assume this is the same range as we had on the Rift S, where the range was expressed as between 0 and 255. For my experiment, I really need to know what intensity is being delivered at a given level - eg what is the actual intensity (or the amplitude) of vibrations at 0.2, 0.5 etc in the scale? In other experiments I've read up, the intensity of a vibration is measured in metres per second per second, which I believe ultimately depends on the amplitude of the vibration (in metres). I've searched the Meta documentation, but can't find any information anywhere - can anyone please tell me the range either of intensity (m/s/s) or amplitude (m). Also, whether the 0 to 1 scale is linear or something else. Alternatively, can anyone point to any documentation that would help, please?
